You have to switch the power supply on via the ATX connector.
The signal "Power Supply On" must be connected to ground to start the power supply.

Ok cool, will use the old wire in green / black to get it to start with motherboard. But otherwise all ok to use two PSU for one system?

Minor detail: Most EVGA PSUs have one color for the entire cable, so you'll probably have to check a pinout diagram carefully to use that trick.

Some of their PSUs also come with a "power-on self-tester," which is essentially a fancy plug just for this purpose.

Ah cool thanks! Will check!

You will need to adapter switches one for each PSU https://www.ebay.com/itm/302406895373. When you connect PSU 1 goes to controller board and then to first hashing board only. second PSU would be connected to remaining hashing boards. Never connect more than 1 PSU to a single hashing board.

Cool thanks man will do! Cheers

Why not just go with a server power supply with a breakout? You can find them on ebay a lot cheaper and more efficient than running 2 power supplies.

From a power standpoint, those 2 PS should work fine.

Higher-end EVGA power supplies some with a "power test" adapter that is basically a "turn the thing on" plug that plugs into the ATX power connector, works well in a mining rig setup.
I'm NOT sure if the GQ line includes that adapter, all of my EVGA are G2 models (I refuse to own any more PS with a "sleeve" type fan bearing, no matter how fancy a name they put on it they ALL die too fast in a high temp environment).

I have no L3 still waiting for the delivery, when I looked to the pictures there are 4 boards.

Use two boards with the first ps and the other two with your second ps.

Hey, according to their website this has 6 PCI-E connectors: https://www.evga.com/products/product.aspx?pn=210-GQ-0750-V1

Think it's the VGA and the SATA ones.

Hmm, you need 9 PCIE connectors... one PSU has 4.

Looking to get two of these: https://www.amazon.co.uk/gp/product/B017RO39TK/ref=ox_sc_act_title_1?smid=A3P5ROKL5A1OLE&psc=1

In order to power my L3+ (and overclock so need higher watts).

Is there anything obvious i'm missing as to why this won't work?

Thanks in advance for any help
